watchfrr is currently being started with $frr_global_options
This is problematic as that it has a entirely different cli
than the rest of the daemons and we have no plans to make
this equivalent.

Add new topology for testing IGMPv2/MLDv1 immediate leave and more features
in the future.
Signed-off-by: Rafael Zalamena <rzalamena@opensourcerouting.org>
(Somewhat) useful when dealing with an interface that has only one host
attached. Only works for IGMPv2 and MLDv1, other protocol versions have
no leave message.

Replace the LSDB callbacks with LSA update and delete hooks using the
the FRR hook mechanism. Remove redundant callbacks by placing the LSA
update and delete hooks in a single place so that deletes don't need
to be handled by the update hook. Simplify existing OSPF TE and OSPF
API Server callbacks now that there is no ambiguity or redundancy.
Also cleanup the debugging by separating out opaque-lsa debugging
from the overloaded event debugging.

When a BGP instance with a manually assigned VPN label is deleted, the
label is not released from the Zebra label registry. As a result,
reapplying a configuration with the same manual label leads to VPN
prefix export failures.
For example, with the following configuration:
> router bgp 65000 vrf BLUE
> address-family ipv4 unicast
> label vpn export <int>
Release zebra label registry on unconfiguration.

In bgp_show_table_rd(), the is_last argument is determined using the
expression "next == NULL" to check if the RD table is the last one. This
helps ensure proper JSON formatting.
However, if next is not NULL but is no longer associated with a BGP
table, the JSON output becomes malformed.
Updates the condition to also verify the existence of the next bgp_dest
table.

evpn route-targets are decoded in ... multiple places; at least

Topology:
A single router is acting as the First Hop Router (FHR), Last Hop Router (LHR), and RP.
RC and Issue:
When an upstream S,G is in join state, it sends a register message to the RP.
If the RP has the receiver, it sends a register stop message and switches to the shortest path.
When the register stop message is processed, it removes pimreg, moves to prune,
and starts the reg stop timer.
When the reg stop timer expires, PIM changes S,G state to Join Pending and sends out a NULL
register message to RP. RP receives it and fails to send Reg stop because SPT is not set at that point.
The problem is when the register stop timer pops and state is in Join Pending.
According to https://www.rfc-editor.org/rfc/rfc4601#section-4.4.1,
we need to put back the pimreg reg tunnel into the S,G mroute.
This causes data to be sent to the control plane and subsequently interrupts the line rate.
Fix:
If the router is FHR and RP to the group,
ignore SPT status and send out a register stop message back to the DR (in this context, the same router).

Currently when the fpm_listener attempts to read say X
bytes it may only get Y( which is less than X ). In this
case we should assume that the dplane_fpm_nl code is just
being slow, as that we know it is possible for it to send
a partial fpm message. Let's just loosen the constraints
a bit and allow data to flow.

Make it consistent and call it `event` when formatting something to

FRR's event loop prints a warning if a timer is executed more than some
given threshold late, default being 4s. Set a more appropriate
threshold for BFD TX timers (half TX interval).
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
Refactor the "timer getting executed too late" warning:
- warning threshold is now adjustable
- check is performed when event actually executes, rather than when it's
thrown on ready list
- ignore_late_timer replaced with threshold = 0
- system load averages printed in log message
- warning ratelimited to once per 10s rather than once per poll()
